Abstract
A high-frequency device comprises a frame (2) provided with walls (12; 9-11) and leg sections (13; 16) extending from said walls. Said device further comprises a printed circuit board (3) extending perpendicularly to said walls, wherein said leg sections extend through holes (14; 19) in said printed circuit board and are connected to the printed circuit board by means of solder. At least one outer side wall of said frame is provided with at least one leg section which extends through a hole located in a part of said printed circuit board, which part extends through said outer side wall.
Description
The present invention relates to a kind of equipment, relate to a kind of high-frequency apparatus especially, it comprises the framework of the shank that possesses wall and extend from described wall, described equipment also comprises the printed circuit board (PCB) that extends perpendicular to described wall, and wherein said shank extends through the hole of described printed circuit board (PCB) and is connected to this printed circuit board (PCB) by the mode of welding.
Such one from UK Patent Application GB-A-2, among the embodiment of 318,690 equipment that can learn, metal framework possesses lateral wall and extends in interior wall between the lateral wall.The interior wall of metal framework possesses hole that extends through printed circuit board (PCB) and the shank that is connected thereto by the mode of welding.Since this shank, this printed circuit board ground.If this equipment is used as the analog or digital receiver, it is very important that printed circuit board (PCB) is surrounded by described framework as far as possible.In addition, also be important with printed circuit board ground to lateral edge.
In known equipment, can not be the lateral wall except lateral edge is directly connected to printed circuit board ground to lateral edge.Because the difference of the thermal coefficient of expansion between printed circuit board (PCB) and the metal framework, the shortcoming of aforesaid way are the connection between printed circuit board (PCB) and this framework and will break.
An object of the present invention is to provide a kind of equipment, particularly a kind of high-frequency apparatus, wherein lateral wall also can be with reliable and easy mode ground connection.
This purpose reaches by equipment according to the present invention, at least one lateral wall of wherein said framework possesses the shank that at least one extends through the hole of a part that is arranged in described printed circuit board (PCB), and the part of described printed circuit board (PCB) extends through described lateral wall.
In this way, whole printed circuit board (PCB) except the described part that possesses described hole can be surrounded by framework, and printed circuit board (PCB) is the shank ground connection of the described lateral wall by described part and described framework simultaneously, and described shank is the hole that is arranged in described part.
Because the part of described printed circuit board (PCB) extends through described lateral wall, it is identical with prior art equipment that the external dimensions of framework keeps.This has such advantage, and this equipment meets with the relevant international standard of the size of equipment as receiver.
Embodiment according to equipment of the present invention is characterised in that described lateral wall possesses at least one and cuts part, and described shank is arranged in this and cuts part and part of printed circuit board (PCB) and extend through this and cut part.
This lateral wall can obtain by punching press at an easy rate, wherein can cut a described lateral wall and cut part with formation, and form shank simultaneously.
Another embodiment according to equipment of the present invention is characterised in that all lateral walls possess the shank in the hole that extends through the part that is arranged in printed circuit board (PCB), and the part of described printed circuit board (PCB) extends through described lateral wall.
In this way, the equipment ground that can obtain to optimize.
Explain the present invention, wherein accompanying drawing here with reference to the accompanying drawings and by way of example in more detail:
Fig. 1 is the exploded view according to equipment of the present invention,
Fig. 2 is the framework of equipment as shown in Figure 1 and the exploded view of printed circuit board (PCB),
Fig. 3 is the perspective view of the equipment shown in Fig. 1,
Fig. 4 is the exploded view according to another framework of equipment of the present invention.
Identical part is by identical numeral.
Fig. 1 is the exploded view according to high frequency of the present invention (hf) equipment 1, the pin piece 5 that it comprises metal framework 2, printed circuit board (PCB) 3, connector 4, is connected to described printed circuit board (PCB) 3 and extends through described framework 2, and two be parallel to that described printed circuit board (PCB) 3 extends and from last and from the lid 6,7 of closed metal framework 2 down.
When this equipment 1 of assembling, framework 2 is connected to printed circuit board (PCB) 3, and shank 13,16 is inserted into and passes hole 14,19 simultaneously.The edge 20 of interior wall 12 is located on the printed circuit board (PCB) 3, and simultaneously lateral wall 8-11 surrounds printed circuit board (PCB) 3 and extends along the edge 21 of printed circuit board (PCB) 3.Part 18 is positioned at and cuts among the part 15, and wherein part 18 has approximate the same big width W with the width that cuts part 15.But the length of part 18 is preferably as much as possible little, but makes the hole 19 that part 18 extends through lateral wall 8-11 and is provided for inserting shank 16 therein.Shank 13,16 is inserted into and passes after the hole 14,19, and shank 13,16 is connected to printed circuit board (PCB) 3 by the mode of welding, thinks that printed circuit board (PCB) 3 provides earthing mode.
By the shank 13 and the shank 16 that is arranged in lateral wall 8-11 of wall 12 extensions internally, provide easy method reliably for printed circuit board (PCB) 3 being connected and being grounding to framework 2.
Fig. 4 shows the framework 2 ' that is similar to framework 2 except comprising additional interior wall 22, and described interior wall 22 has shielded harmful vibration of IF output.
Claims (3)
1. equipment, it comprises the framework of the shank that possesses wall and extend from described wall, described equipment also comprises the printed circuit board (PCB) that extends perpendicular to described wall, wherein said shank extend through in the described printed circuit board (PCB) the hole and by the welding mode be connected to this printed circuit board (PCB), at least one lateral wall of wherein said framework possesses the shank that at least one extends through the hole of a part that is arranged in described printed circuit board (PCB), and the part of described printed circuit board (PCB) extends through described lateral wall.
2. high-frequency apparatus as claimed in claim 1, wherein said lateral wall possess at least one and cut part, and described shank is arranged in the described part that cuts part and printed circuit board (PCB) and extends through the described part that cuts.
3. high-frequency apparatus as claimed in claim 1 or 2, wherein all lateral walls possess the shank in the hole that extends through the part that is arranged in printed circuit board (PCB), and the part of described printed circuit board (PCB) extends through described lateral wall.
